HORN=PLATE FOR CAR AND LOCOMOTIVE FRAMES.

SPECIFICATION forming part of Letters Patent No. 34:1,802, dated May 11,1886.

Applicalion filed January 19, 1886. Serial No. 189,069. (No model.)Patented in Belgium January 5, 1886. No. 71,503,

and in Canada February 2, 1886, No. 23,317. v

To all whom it may concern:

Be it known that I, SAMSON FOX, a subject of the Queen of Great Britainand Ireland, re-

siding at Harrogate, in the county of York, Kingdom of Great Britain andIreland, have invented new and useful Improvements inthe Manufacture ofFrame or Horn Plates for Rolling Stock, of which the following is aspecification.

My present invention illustrated by the accompanyi ng drawings, Figures1 to 8,in-clusive, has for object the production in a novel manner offrame or horn plates of any desired form for locomotives or otherrolling-stock.

Fig. 1 represents a plain plate cut to an approximate shape ready to beheated and subjected to a pressing or stamping process according to myinvention, as hereinafter explained, to produce a flanged frame or hornplate having a number of recesses for the reception of aXlcbOXes. Fig. 2shows in side elevation a frame or horn plate so produced. Fig. 3 is anend elevation. cal section on the line a a, and Fig. 5 a verticalsection on the line b b. Fig. 6 represents a plain plate cut as abovereferred to for the formation of a single horuplate. Fig. 7 is a sideelevation of the same after being heated and pressed or stamped andflanged, and Fig.

Sis an endview of Fig. 7.

In the manufacture of frame or horn plates for locomotives and otherrolling-stock in the ordinary way, a plain plate ofinetal is subjectedto the action of sundry machines for imparting to it by variousoperations the required shape, and afterward supplementary parts areadded to give additional strength where needful-as, for instance, uponand near the horns, or in the neighborhood of the recesses for thereception of the axle-boxes. Now, according to my invention a frame orhorn plate of the desired form with flanges to give it the requiredstrength and rigidity is made of a single plate of metal by pressing orstamping. A plate of metal, such as mild steel, (which may be somewhatthinner than would be necessary for the manufacture of a frame-plate ofordinary kind,) is cut roughly to approximately the required form,butsomewhat larger than the finished frame is intended to bc-for example,as represented in Fig. 4 is a verti Figs. 1 or 6. Then it is heated to asuitable temperature for being pressed or stamped to the required shapewith flange or flanges, and while hot it is subjected to the action ofsuit able pressing or stamping apparatus,whereby there is imparted to itthe desired shape, the edges being formed into a flange or flanges forexample, as represented in Figs. 2-, 3, 4, and 5, and in Figs. 7 and 8,whereby the necessary strength and rigidity is imparted to the whole,and care being taken to prevent buckling or warping during thesubsequent cooling and consequent contraction. The edge or edges of theflange or flanges is or are subsequently trimmed.

In carrying out my invention the requisite formation of the plate may beproduced by the use of male and female dies with apparatus to preventwarping or buckling, such as described in the specification of my otherapplication for patent, bearing even date herewith, No. 189,070.According to the inven tion described in that specification, I use afemale die or matrix having an internal configuration corresponding tothe external form required to be imparted to the frameplate, and inconjunction with this female die or matrix I use a male die ofcorresponding external form, but smaller to such an eX- tent that whenthe male die is within the female die or matrix, there remains or remainbetween them a space or spaces of a width corresponding to the thicknessofplate to be operated upon, such space extending entirely around themale die, where the frame or horn plate is to be made witha singleflange extending entirely around it. By hydraulic or other power one orboth of the dies is or are operated so thataplate pressed between themhas its edges turned up or flanged and passes through the female dieonto blocks or supports able to move freely in all directions parallelwith the face of the flanged plate, to which end the blocks or platesare arranged to rest upon anti-friction balls. Above the flangedplateother blocks or plates are placed, and these are by the male die orhead of the press caused to bear against the flanged plate, so that itis held or squeezed between the blocks situate above and below it insuch manner as to ad mit of the cooling and contraction, but to preventwarping or buckling, to which end antifriction balls are introducedbetween each pair of plates forming the upper blocks or pressers andwhich are acted upon by the male die or head of the press during suchcooling. As will be evident, the forms of the dies will depend upon theform, proportions, and dimensions of the frame or horn plate to beproduced.

WVhat I claim is- 1. The mode or process of manufacturing frame or hornplates for rolling stock,which consists in first cutting a suitableplate to approximately the form of the intended frame or horn plate,afterward heating the said plate, then pressing or forcing it by meansof a male die into and through a female die, thereby iniparting to itthe desired form and flanging it, and afterward causing it to be heldbetween pressers or holders to prevent warping or buckling,substantially as described.

2. As a new article of manufacture,aflanged frame or horn plate forrolling stock, formed of asingle plate by pressing or stamping,substantially as described.
